Anyone tried to make these in grav sim yet? Does anyone have the most up to date info on them too? All I can find is on wiki right now, but it doesn't look like there's much information available yet (no eccentricities for the HR 8799 system).

Maybe there's stuff to discover about the system with Gravity Simulator. The wiki page talks about a brown dwarf at 5 AU, and that its eccentricity may have implications on the structure of the dust cloud.
